Transmission of media keys

1. A method of transmitting an electronic media key, the method comprising: indicating, on a first device, initiation of transmission of an electronic media key to the first device from a second device, the electronic media key comprising a data identifier and a decryption key, wherein the data identifier is used to locate and access encrypted media data associated with the electronic media key, the decryption key usable for decrypting the encrypted media data, wherein the data identifier points to a location where the encrypted media data is stored, and wherein the location is remote from the electronic media key and the first device; receiving, by the first device, the electronic media key from the second device; and upon the first device receiving the electronic media key from the second device, printing a physical media key including machine readable information, the machine readable information including the data identifier and the decryption key included in the electronic media key.

2. The method of claim 1 further comprising printing the decrypted media data corresponding to the data identifier.

3. The method of claim 1 further comprising displaying the decrypted media data corresponding to the data identifier on a digital display.

4. The method of claim 1 further comprising: communicating the electronic media key from the first device to a third device.

5. The method of claim 4 wherein the communicating comprises communicating the electronic media key to the third device when a set of one or more conditions is met.

6. The method of claim 1 further comprising: upon the first device receiving the electronic media key from the second device: accessing the encrypted media data using the data identifier included in the electronic media key; decrypting the accessed encrypted media data using the decryption key included in the electronic media key to produce decrypted media data; and outputting the decrypted media data.

7. The method of claim 1 further comprising: indicating on the first device, separate from indicating the initiation of transmission of the electronic media key from the second device, completion of the transmission of the electronic media key from the second device to the first device.

8. A device comprising: an indicator component configured to indicate initiation of transmission of an electronic media key to the device from a second device, the electronic media key comprising a data identifier and a decryption key, the data identifier is used to locate and access encrypted media data associated with the electronic media key, the decryption key usable for decrypting the encrypted media data, wherein the data identifier points to a location where the encrypted media data is stored, and wherein the location is remote from the electronic media key and the first device; and a printer component configured to, upon receiving, by the device, the electronic media key from the second device, print a physical media key including machine readable information, the machine readable information including the data identifier and the decryption key included in the electronic media key.

9. The device of claim 8 further configured to print the decrypted media data accessed using the data identifier included in the electronic media key.

10. The device of claim 8 further comprising a display configured to display the decrypted media data accessed using the data identifier.

11. The device of claim 8 further comprising: a module configured to communicate the electronic media key from the device to a third device.

12. The device of claim 11 wherein the module is configured to communicate the electronic media key to the third device when a set of one or more conditions is met.

13. The device of claim 8 wherein the first indicator component includes a light emitting diode.

14. The device of claim 8 further configured to: access the encrypted media data using the data identifier included in the electronic media key; decrypt the accessed encrypted media data using the decryption key included in the electronic media key to produce decrypted media data; and output the decrypted media data.

15. The device of claim 8 further comprising: a second indicator component indicating completion of the transmission of the electronic media key from the second device to the device.

16. A method comprising: indicating, using a first indicator on a first device, initiation of transmission of an electronic media key to the first device from a second device, the electronic media key comprising a data identifier and a decryption key, the data identifier used to locate and access encrypted media data associated with the electronic media key, the decryption key usable for decrypting the encrypted media data, wherein the data identifier points to a location where the encrypted media data is stored, and wherein the location is remote from the electronic media key and the first device; upon the first device receiving the electronic media key from the second device: accessing, by the first device, the remotely stored encrypted media data using the data identifier included in the electronic media key; decrypting, by the first device, the accessed encrypted media data using the decryption key included in the electronic media key to produce decrypted media data; and outputting, by the first device, the decrypted media data.

17. The method of claim 16 further comprising: indicating, using a second indicator provided on the first device separately from the first indicator, completion of the transmission of the electronic media key from the second device to the first device.

18. The method of claim 16 further comprising: upon receiving the electronic media key by the first device from the second device, printing a physical media key comprising machine readable information, the machine readable information including the data identifier and the decryption key included in the electronic media key.

19. The method of claim 16 wherein: the first device is a digital projector; and the outputting comprises outputting the decrypted media data using the projector.

20. The method of claim 16 wherein the first device is a printer.
